I know their important but how important and what exercises can I do improve them? The only exercises know to improve lungs are to hold breath underwater, and to take inhale (as much as possible) and hold a few sec then exhale (as much as possible) and hold again. And by long distance, I mean 2.4 miles or so.
So, how affective are those things for improving your lungs and what are some other things that can be done? Also, I do not smoke nor have I even smoked (not even 1 puff, no 2nd hand smoke either). Thumbs-up rating for every helpful answer.
